I think a Pythoneer will twistedly think at this point is: why do you
say "can't use" we can can just *redefine* __add__, __sub__, other
__ribs__, to suit, get whatever meanings for those typical arithmetic
operators you like.

But in Python, we have been, given looping constructs (it's a VHLL ya know,
not an assembly language like Scheme and/or MMIX).
